Flight computer arrived

this is needed as part of my Navigation theory syllabus. I always liked the idea of a slide rule, and being required to use one is actually fun for me. It needs no batteries to operate!

It's nice to see it being taught as these were dropped out of school syllabus for my generation in favour of calculators.

This officially kicks off my navigation ground school learning. Have to say this subject is not boring at all, and I think I'll come to appreciate the Longitude story more.

P/S I don't know how to use it yet
